According to an embodiment, an order of operations S310 through S390 may be changed, or some operations may be skipped.

FIG. 4 is a flowchart illustrating a method of registering the external device 200 in the management server 300 by connecting the external device 200 to an account, according to an exemplary embodiment.

In operation S410, the host device 100 may determine physical connection with the external device 200. The physical connection may be an active connection, a passive connection, a remote connection, a wired connection, a wireless connection, or a short-range communication connection.

In operation S420, the host device 100 may authenticate the external device 200. For example, the host device 100 may authenticate the external device 200 based on authentication information received from the external device 200.

The authentication information is used to authenticate whether the external device 200 is controllable by an application executed in the host device 100, or to authenticate whether the external device 200 is allowed to be connected to the host device 100. When the number of external devices 200 connectable to the host device 100 is N, the N external devices 200 may include the same number of pieces of authentication information.

The external device 200 may also authenticate the host device 100 based on authentication information received from the host device 100. The authentication information received from the host device 100 may be used to authenticate whether an application is installable in the host device 100 or to authenticate whether the host device 100 is allowed to receive measurement information measured by the external device 200.

In operation S430, the host device 100 may determine whether the external device 200 that is physically connected is an external device whose account needs to be registered. For example, when an account needs to be used for the external device 200 to synchronize measurement information with the management server 300, the host device 100 may determine that the external device is an external device whose account needs to be registered. Also, when an account registration request is received from an external device 200 that is physically connected, the host device 100 may determine that the external device 200 is an external device whose account needs to be registered.

When the external device 200 that is physically connected is an external device whose account needs to be registered, the host device 100 may log in to the management server 300 in operation S440. In other words, the host device 100 may transmit account information (for example, an ID and a password) to the management server 300.

If the login succeeds based on the account information of the host device 100 in operation S450, the host device 100 may transmit registration request information on the external device 200 to the management server 300 in operation S460. Here, the management server 300 may connect to and register the account information of the external device 200.

FIGS. 5A through 5D are diagrams of a user interface (UI) for automatically detecting the external device 200 and registering the external device 200 in the management server 300, according to an exemplary embodiment.

As shown in FIG. 5D, when the external device 200 (for example, Accessory K) is registered in the management server 300, the host device 100 may display the list 510 to which ID information (for example, ‘Accessory K’) of the newly registered external device 200 is added.

FIGS. 6A through 6D are diagrams of a UI for registering the external device 200 in the management server 300, according to an exemplary embodiment.

As shown in FIG. 6A, when “auto-detect” is not set, the host device 100 may not output the “auto-detect” 520 even when the external device 200 is found in the vicinity of the host device 100, but may add and manage ID information of the external device 200 to a list 610 of external devices found nearby the host device 100. When a user gesture requesting for the list 610 is detected, the host device 100 may provide the list 610. Here, the user may select and register an external device, such as Accessory 12, from the list 610.

As shown in FIG. 6B, when a selection (for example, a tap gesture) of the user on the Accessory 12 from the list 610 is detected, the host device 100 may output a window 620 inquiring whether to register the Accessory 12 in the management server 300. Here, the host device 100 may receive a registration request of the user on the Accessory 12.

As shown in FIG. 6C, when the Accessory 12 is a device whose account needs to be registered, the host device 100 may display a window 630 for the user to input account information. The host device 100 may receive the account information (for example, ID: abcd@edf.hci, password: ****) from the user and transmit the received account information to the management server 300, while requesting to register the Accessory 12.

As shown in FIG. 6D, when the Accessory 12 is registered in the management server 300, the host device 100 may display a list 640 of external devices, to which ID information (for example, ‘Accessory 12’) of the newly registered external device, is added.

FIGS. 7A through 7D are diagrams of a UI for providing information about the external device 200, according to an exemplary embodiment.

As shown in FIG. 7A, when a user gesture requesting a list 710 of external devices found nearby is detected, the host device 100 may provide the list 710. Here, the user may select an external device, such as Accessory 12, from the list 710.

As shown in FIG. 7B, when a selection (for example, a swipe gesture) of the user on the Accessory 12 is detected from the list 710, the host device 100 may provide detailed information about the Accessory 12. For example, the host device 100 may provide ID information of a selected external device, a type of a selected external device, capability provided by a selected external device, and information about a category. Here, the user may check the detailed information about the Accessory 12, and determine whether to register Accessory 12 in the management server 300.

As shown in FIG. 7C, the host device 100 may output a window 720 inquiring whether to register the Accessory 12 in the management server 300. Also, the host device 100 may receive a registration request of the user on the Accessory 12.

As shown in FIG. 7D, when the Accessory 12 is registered in the management server 300, the host device 100 may display a list 730 of registered external devices to which ID information (for example, ‘Accessory 12’) of the newly registered external device is added.

FIG. 8A through 8C are diagrams of a UI for releasing registration of the external device 200, according to an exemplary embodiment.

As shown in FIG. 8A, the host device 100 may provide a list 810 of external devices registered in the management server 300 to a user. Here, the host device 100 may detect a user input (for example, a swipe gesture) for selecting an external device, such as Accessory 1, from the list 810.

As shown in FIG. 8B, the host device 100 may provide detailed information about the Accessory 1. For example, the host device 100 may provide ID information of a selected external device, a type of a selected external device, capability provided by a selected external device, and information about a category. Here, the user may check the detailed information and determine whether to release the registration of the Accessory 1.

As shown in FIG. 8C, the host device 100 may output a window 820 inquiring whether to release the registration of the Accessory 1. Also, the host device 100 may receive a registration release request of the user on the Accessory 1. Here, the host device 100 may transmit the registration release request to the management server 300, and delete the Accessory 1 from the list 810.

FIGS. 9A through 9C are diagrams of a database (DB) of the management server 300, according to exemplary embodiments.

As shown in FIG. 9A, according to an embodiment, the management server 300 may hierarchically manage the external devices 200 by mapping the external devices 200 to account information and ID information of the host device 100. A plurality of host devices may be connected to one account or a plurality of external devices may be connected to one host device. Alternatively, one external device may be connected to a plurality of host devices or a plurality of accounts. For example, a scale that is the external device 200 may be connected to each of a mother's device (or a mother's account) or a father's device (or a father's account). Thus, a family may commonly use the external device 200, i.e., the scale. Here, measurement information measured by the external device 200, i.e., the scale, may be managed according to accounts.

As shown in FIG. 9B, according to another embodiment, the management server 300 may classify and manage the host device 100 or the external device 200 according to accounts (refer to Database 1), or may classify and manage the host device 100 or accounts according to external devices (refer to Database 2).

Also, the management server 300 may set and manage a plurality of external devices as one external device group, or set and manage a plurality of host devices as one host device group.

Alternatively, the management server 300 may manage information about the registered external device 200 by using an inner storage unit or an external server.

As shown in FIG. 9C, according to another embodiment, the management server 300 may add a flag 910 to an external device 200 that transmitted measurement information to the management server 300, from among the registered external devices 200. Here, the management server 300 may manage the measurement information measured by the external device 200. The measurement information may include at least one of physical information, administration information, environment information, meal information, exercise information, and state information of consumables used in an external device. A method of the management server 300 collecting measurement information measured by the external device 200 will now be described in detail.

FIG. 10 is a flowchart illustrating a method of the host device 100 transmitting measurement information to the management server 300, according to an exemplary embodiment.

In operation S1010, the host device 100 may obtain measurement information measured by the at least one external device 200. According to an embodiment, the host device 100 may receive the measurement information from the external device 200 through a wired communication, a wireless communication, or a short-range communication (for example, Bluetooth or WLAN).

In operation S1020, the host device 100 may request authentication from the management server 300. For example, the host device 100 may request authentication any may transmit at least one of account information and ID information of the host device 100 to the management server 300.

In operation S1030, the host device 100 may determine whether the authentication succeeds based on a response of the management server 300 regarding the request. If the authentication failed, the host device 100 may request authentication again by transmitting the account information and/or the ID information of the host device 100 to the management server 300.

In operation S1040, if the authentication succeeded, the host device 100 may transmit the measurement information measured by the at least one external device 200 to the management server 300. Here, the host device 100 may transmit only a part of the obtained measurement information to the management server 300.

In other words, according to an embodiment, the management server 300 may collect the measurement information measured by the external device 200 only through the authenticated host device 100. For example, since it is important secure health information, such as personal medical information or personal physical information, only the authenticated host device 100 is able to transmit the measurement information to the management server 300, as will be described in detail with reference to FIG. 11.

FIG. 11 is a flowchart illustrating a method of the management server 300 receiving measurement information of the external device 200 through the authenticated host device 100, according to an exemplary embodiment.

In operation S1110, the host device 100 may be connected to the external device 200 through second short-range communication (for example, Bluetooth or WLAN). Then, in operation S1120, the external device 200 may measure health-related information of a user. Here, the measuring may include collecting surrounding environment information or receiving information from the user. According to an embodiment, an order of operations S1110 and S1120 may be changed.

In operation S1130, the external device 200 may transmit the measurement information to the host device 100. The host device 100 may transmit the measurement information periodically or when a certain event is generated. Examples of the certain event include an input event from the user and an event generated when a measured value exceeds a predetermined range.

The external device 200 may encode and transmit the measurement information to the host device 100.

In operation S1140, when the measurement information is received from the external device 200, the host device 100 may request to be authenticated by the management server 300. For example, the host device 100 may request authentication while transmitting at least one of account information (ID and password) and ID information of the host device 100 to the management server 300.

In operation S1150, the management server 300 may perform authentication based on at least one of the account information and the ID information of the host device 100, in response to the authentication request of the host device 100. For example, the management server 300 may compare the account information or ID information received from the host device 100 with pre-registered information, and perform authentication of the host device 100.

In operation S1160, if the authentication succeeds, the host device 100 may transmit the measurement information obtained from the external device 200 to the management server 300. According to an embodiment, whenever the measurement information is transmitted to the management server 300, the host device 100 may request to be authenticated by the management server 300. Also, the host device 100 may transmit the measurement information to the management server 300 several times based on having been authenticated once if the connection to the management server 300 is maintained.

In operation S1170, the management server 300 may store the measurement information. Here, the management server 300 may classify and store the measurement information according to the external devices 200, according to account information, or according to the host devices 100.

In operation S1180, the management server 300 may analyze the measurement information. In operation S1190, the management server 300 may manage the at least one external device 200 based on the measurement information. Here, the management server 300 may determine a health state of the user by using the measurement information, or may generate food recommendation information, exercise recommendation information, a warning, or an alarm for the user, as will be described in detail below.

FIG. 12 is a flowchart illustrating a method of the host device 100 filtering measurement information to be transmitted to the management server 300, according to an exemplary embodiment.

In operation S1210, the host device 100 may be connected to the external device 200 via a wired or wireless communication. In operation S1220, the external device 200 measures health-related information of a user, and in operation S1230, the host device 100 may receive measurement information measured by the external device 200. Since operations S1210 through S1230 correspond to operations S1110 through S1130 of FIG. 11, details thereof will not be repeated here.

In operation S1240, the host device 100 may filter the obtained measurement information according to a predetermined standard. According to an embodiment, the host device 100 may extract a part of the measurement information based on whether the at least one external device 200 that transmitted the measurement information is a medical device. For example, the host device 100 may classify the measurement information measured by the external device 200 defined to be a medical device not to be transmitted to the management server 300. In other words, since measurement information measured by the medical device is very private information, the host device 100 may block the measurement information from being transmitted to the management server 300 to prevent the measurement information from being exposed.

Alternatively, the host device 100 may filter the measurement information based on whether a route for transmitting the measurement information is a secure network. For example, the host device 100 may extract only measurement information obtained through a secure network as the part of measurement information to be transmitted to the management server 300.

According to another embodiment, the host device 100 may extract a part of the measurement information based on a pre-set type of measurement information. For example, the host device 100 may pre-receive a selection of the user with respect to a type of measurement information to be transmitted to the management server 300. Also, the host device 100 may compare the type of the obtained measurement information and the type of the pre-selected measurement information to filter the obtained measurement information.

In operation S1250, the host device 100 may transmit the part of measurement information to the management server 300. In operation S1260, the management server 300 may store the part of measurement information in a DB. Also, in operation S1270, the management server 300 may analyze the part of measurement information to determine a health state of the user. In operation S1280, the management server 300 may manage the at least one external device 200 based on the part of the measurement information.

FIG. 13 is a diagram for describing a method of filtering measurement information based on whether the external device 200 is a medical device, according to an exemplary embodiment.

As shown in FIG. 13, the external device 200 may include a sensing unit, a control unit, and an authentication chip. The sensing unit may measure a surrounding environment or a health state of a user by using various sensors, or may detect information input from the user.

The control unit may transmit measurement information sensed by the sensing unit to the host device 100, together with authentication information stored in the authentication chip. Here, the authentication information stored in the authentication chip may include identification code indicating that the external device 200 is a medical device.

Accordingly, the host device 100 may check the authentication information received from the external device 200, and determine that the external device 200 that transmitted the measurement information is a medical device. When the external device 200 that transmitted the measurement information is determined to be a medical device, the host device 100 may not transmit the measurement information to the management server 300.

Meanwhile, in order to secure the measurement information, the external device 200 may encode the measurement information by using an encoding code pre-negotiated with the management server 300 or the medical device (for example, a doctor's device, a pharmacist's terminal, or a medical institute server), and transmit the encoded measurement information to the host device 100. Here, the pre-negotiated encoding code may be stored in the authentication chip.

When the encoded measurement information is received from the external device 200 through the host device 100, the management server 300 may decode the encoded measurement information through an authentication module and store the decoded measurement information in a storage unit. The external device 200 may directly transmit the encoded measurement information to the management server 300.

Also, when the measurement information is medical data, the external device 200 may encode the measurement information according to a medical information standard (for example, HL7, DICOM, or IEEE11073), and transmit the encoded measurement information to the host device 100. When the host device 100 transmits the encoded measurement information to the management server 300, the management server 300 may decode the encoded measurement information.

FIG. 14A through 14C are diagrams of a UI of the host device 100 for receiving a selection from a user with respect to a type of measurement information to be transmitted to the management server 300, according to an exemplary embodiment.

As shown in FIG. 14A, the host device 100 may add a management server account according to a user request. Then, as shown in FIG. 14B, the host device 100 may determine whether to synchronize the management server account. In other words, the host device 100 may automatically transmit the measurement information of the external device 200 to the management server 300 by using the management server account. The host device 100 may upload the measurement information at regular cycles, or may upload the measurement information to the management server 300 when the measurement information is obtained.

As shown in FIG. 14C, the host device 100 may provide a setting window for setting a type of measurement information to be transmitted to the management server 300 through a predetermined application. Here, the user may select a synchronization parameter to be transmitted to the management server 300 through the setting window. For example, the user may select blood pressure and a weight as synchronization parameters to be transmitted to the management server 300. Here, from among the measurement information, the host device 100 may transmit blood pressure and a weight to the management server 300 and may not transmit a heart rate to the management server 300.

FIG. 15 is a flowchart illustrating a method of the external device 200 directly transmitting measurement information to the management server 300, according to an exemplary embodiment.

In operation S1510, the external device 200 may measure health-related information of a user. Also, the external device 200 may measure surrounding environment information or remaining state information of consumables (such as a blood sugar strips) or medicines (such as insulin).

In operation S1520, the external device 200 may request authentication information from the host device 100 so as to directly communicate with the management server 300. In response to the request, the host device 100 may transmit the authentication information to the external device 200 in operation S1530. For example, the host device 100 may transmit at least one of account information (for example, an ID and a password) and ID information (for example, a device ID) of the host device 100 to the external device 200, as the authentication information.

In operation S1540, the external device 200 may request that the host device be authenticated by the management server 300 while transmitting the authentication information (for example, the account information or the ID information of the host device 100) obtained from the host device 100 to the management server 300.

In operation S1550, in response to the request for authentication, the management server 300 may perform authentication on at least one of the account information and the ID information of the host device 100. For example, the management server 300 may compare the account information or the ID information received from the external device 200 with pre-registered information to perform the authentication.

In operation S1560, when the authentication succeeds, the external device 200 may transmit the measurement information to the management server 300. According to an embodiment, the external device 200 may request that the host device be authenticated by the management server 300 whenever the measurement information is transmitted to the management server 300. Alternatively, the external device 200 may transmit the measurement information to the management server 300 several times based on a single authentication while the external device 200 and the management server 300 are maintained to be connected to each other.

In operation S1570, the management server 300 may store the measurement information. Here, the measurement server 300 may classify and store the measurement information according to the external devices 200, according to account information, or according to the host device 100 to which the external device 200 is connected.

In operation S1580, the management server 300 may analyze the measurement information and determine a health state of the user.

FIG. 16 is a diagram for describing the management server 300 collecting exercise information of a user, according to an exemplary embodiment.

As shown in FIG. 16, exercise information measured in a bicycle 1610, a dumb-bell 1620, a hula hoop 1630, and a bench press 1640 may be transmitted to the management server 300 through the host device 100, or directly to the management server 300. The bicycle 1610, the dumb-bell 1620, the hula hoop 1630, and the bench press 1640 may each include a sensing unit for measuring exercise information and a communication unit for communicating with the host device 100 or the management server 300. For example, the bicycle 1610, the dumb-bell 1620, the hula hoop 1630, and the bench press 1640 may each include a motion sensor, an acceleration sensor, an NFC tag, or a BLE tag, but are not limited thereto.

FIGS. 17A through 17C are diagrams for describing the management server 300 collecting meal information of a user, according to an exemplary embodiment.

As shown in FIG. 17A, when the user tags a personal device 1720 (for example, an employee ID, a student ID, or a mobile phone) to a kiosk 1710 in a restaurant, the personal device 1720 may obtain diet information from the kiosk 1710, and transmit the obtained diet information to the management server 300. Here, the personal device 1720 may transmit the diet information to the management server 300 directly or through the host device 100. The personal device 1720 may transmit the diet information to the management server 300, together with account information. The management server 300 manages a diet and a meal portion of the user through the account information.

As shown in FIG. 17B, the host device 100 obtains the diet information from the personal device 1720 or the management server 300, and may output the obtained diet information on a screen. Alternatively, the management server 300 may obtain the diet information directly from the kiosk 1710.

FIG. 18 is a flowchart illustrating a method of the host device 100 transmitting measurement information to the management server 300 in an emergency, according to an exemplary embodiment.

In operation S1810, the host device 100 may detect a physical connection to the external device 200. Here, in operation S1815, the host device 100 may determine whether a current mode is an emergency mode. According to an embodiment, the emergency mode may be activated via an input of a user of the external device 200 or via remote control.

In operation S1820, when the current mode is not an emergency mode, the host device 100 may perform a general account login process. In operation S1825, when the current mode is an emergency mode, the host device 100 may request to be authenticated by the management server 300 by using emergency account information. An emergency account may be operated separately from a personal account. In operation S1830, the management server 300 may perform authentication on the emergency account information.

In operation S1835, the external device 200 may measure health-related information of the user. Then, in operation S1840, the external device 200 may transmit measurement information to the host device 100.

In operation S1845, the host device 100 may transmit the measurement information obtained from the external device 200 to the management server 300 through the emergency account. The management server 300 may analyze the measurement information in operation S1850, and the management server 300 may transmit a result of the analyzing to the host device 100 in operation S1855. Then, the host device may display the result on a screen. Examples of the result may include current state information of the user, information for dealing with an emergency, and a type of measurement information that is additionally required.

In operation S1860, the management server 300 may transmit the measurement information to an external server, for example, a medical institute server, and obtain diagnosis/prescription information from the external server. Then, the management server 300 may transmit the diagnosis/prescription information to the host device 100. In an emergency, the host device 100 may transmit health information measured by another user using the external device 200 to the management server 300 or a medical institute server by using emergency account information, and receive suitable feedback from the management server 300 or the medical institute server.

According to an embodiment, an order of operations S1810 through S1860 may be changed, or some operations may be omitted.

FIG. 19 is a flowchart illustrating a method of the host device 100 generating a control command for controlling the external device 200, according to an exemplary embodiment.

In operation S1910, the host device 100 may obtain measurement information from the external device 200. In operation S1920, the management server 300 may authenticate the host device 100. If the authentication succeeds, the host device 100 may transmit the measurement information obtained from the external device 200 to the management server 300 in operation S1930. Since operations S1910 through S1930 correspond to operations S1110 through S1130 of FIG. 11, details thereof will not be repeated here.

In operation S1940, the management server 300 may analyze the measurement information measured by the external device 200. According to an embodiment, the management server 300 may analyze a current health state of the user by comparing the measurement information measured by the external device 200 and pre-stored health information, such as a PHR.

Alternatively, the management server 300 may determine a health state of the user by comparing measurement information of other users having a similar disease and the measurement information measured by the external device 200.

The management server 300 may transmit the measurement information to an external server, such as a medical institute server, and receive diagnosis/prescription information corresponding to the measurement information to analyze the health state of the user.

For example, the management server 300 may determine the health state of the user by analyzing measurement information, such as blood pressure or blood sugar, obtained through the external device 200, such as a blood pressure gauge or a blood sugar meter. Alternatively, the management server 300 may calculate a suitable exercise amount for the user in association with an EMR, and compare the calculated suitable exercise amount with an actual exercise amount measured by a sporting apparatus. Here, the management server 300 may analyze whether the actual exercise amount is insufficient or excessive based on a result of the comparison.

The management server 300 may analyze environment information (for example, a temperature or humidity) measured by the external device 200 including an environment sensor, or may determine a replace cycle of a strip of a blood sugar meter or medical consumables like insulin.

The touch screen module 163 may detect a user's touch gesture on a touch screen and transmit information about the touch gesture to the control unit 150. The touch screen module 163 may be implemented as a separate hardware controller.

Various types of sensors may be disposed inside or near the touch screen, in order to detect a touch or a proximity touch on the touch screen. An example of a sensor for detecting a touch on the touch screen may be a tactile sensor. A tactile sensor is a sensor for detecting a contact of a specific object to such a degree that humans may feel it or to a higher degree. The tactile sensor may detect various types of information such as information about a roughness of a contact surface, a hardness of a contact object, or a temperature at a contact point.

Touch gestures of a user may be a tap, a touch and hold, a double-tap, a drag, panning, a flick, a drag-and-drop, and a swipe.

A “tap” is a gesture in which a user touches a screen by using a finger or a touch tool, for example, an electronic pen, and then, immediately lifts it off from the screen without dragging on the screen.

A “touch and hold” is a gesture in which a user touches a screen by using a finger or a touch tool, for example, an electronic pen, and holds the touch for more than a critical period of time, for example, 2 seconds. That is, a difference in time between time points of a touch on and a lift-off from the screen is longer than the critical period of time, for example, 2 seconds. If the touch input is held for more than the critical period of time to make a user recognize whether the touch input is a tap or a touch and hold, a feedback signal may be visually, aurally, or tactually provided. The critical period of time may vary according to exemplary embodiments.

A “double tap” is a gesture in which a user touches a screen twice by using a finger or a touch tool which may be a stylus.

A “drag” is a gesture in which a user touches a screen by using a finger or a touch tool and moves the finger or the touch tool to another location in the screen while holding the touch. When the drag is performed, an object moves, or a panning gesture, which is described below, is performed.

A “panning” gesture is a gesture in which a user performs a drag without selecting an object. As the panning does not select a specific object, an object does not move in a page, and the page moves in the screen or a group of objects moves in the page.

A “flick” is a gesture in which a user performs a drag at a critical speed or at a higher speed, for example, 100 pixels per second, by using a finger or a touch tool. The flick may be distinguished from the drag or the panning based on whether a moving speed of a finger or a touch tool is equal to or higher than the critical speed, for example, 100 pixels/s.

A “drag and drop” is a gesture in which a user drags an object to a predetermined place in a screen by using a finger or a touch tool, and then, lifts the finger or touch tool off the screen.

A “pinch” is a gesture in which a user touches a screen with two fingers and moves the two fingers in different directions. The pinch may be a pinch-open gesture for zooming-in to an object or a page, or a pinch-close gesture for zooming-out from an object or a page. A zoom-in or zoom-out value is determined according to a distance between the two fingers.

A “swipe” is a gesture for touching an object in a screen by using a finger or a touch tool and moving the finger or the touch tool in a horizontal or vertical direction for a certain distance. Moving in a diagonal direction may or may not be recognized as a swipe event.

The memory 160 may include a voice recognition module (not illustrated) for recognizing a voice of a user by using a voice recognition engine and transmitting the recognized voice signal to the control unit 150.

The alarm module 164 may generate a signal for notifying generation of an event in the host device 100. Examples of the event generated in the host device 100 may include call signal reception, message reception, key signal input, and schedule notification. The alarm module 164 may output an alarm signal in the form of a video signal via the display unit 121 or in the form of an audio signal via the sound output unit 122. The alarm module 164 may also output an alarm signal in the form of a vibration signal via the vibration motor 123.

The alarm module 164 may provide a snooze function. For example, if a user sets the number of alarm repetitions to be, for example, 5 times, or an alarm interval to be, for example, 3 minutes, the alarm module 164 may output an alarm signal by a predetermined number of times, for example, 5 times, or at a predetermined interval, for example, every 3 minutes.

The application module 165 may be connected to an application DB or an external device DB. The application DB may store applications for controlling the external device 200, but is not limited thereto. For example, the application DB may store a healthcare application for managing a medical device, a fitness application for controlling a sporting apparatus, and a reminder application for outputting a notification. The external device DB may store device information about the external device 200 and measurement information measured by the external device 200.

The application module 165 may control the external device 200 by using the application for controlling the external device 200. Also, the application module 165 may provide the application for controlling the external device 200 to the management server 300.
